HiQDDLE- FRAME.

Specification of Letters Patent.

Patented Feb. 23, 1915..

Application f led July 23, 131 Serial No.

To all whom it may concern I Be known that LJOnN WAL ER, J12, a citizenbf theUnited States, residing in Philadelphia, Pennsylvania, haveinvented certain Improvements in Heddle Frames, of lwhich'the followingis a specification.

One objectof my invention is to produce a durable and inenpensi've'hddleframe for .lqgims in which the ,heddles may be freely ifi ived in orderthat the weaver can easily get hold'of the portions of the ,warp'threadsback of the heddleframe or when for any other reason it isldesiijed'tomove the heddles or change their positionin the frame.

. Another object of'the invention is ,to so construct the device thatthe means which peifinit the movement of the heddles shall not interfere-"with the necessary free movement of the heddle frames during theiralternate rising falling 'movement under opera-ting conditions.

i A still further obj ect of the invention is to prevent oneheddlefra'me from injuring another during the operation in the loom.

'lfhes eobjects aridother advantageous ends I attain as hereinafter setforth reference bein'gh ad tothe accqmpanying drawing in which,

Figure 1 is an elevation of a heddle frame showing inventio n appliedthereto;

Qis an enlarged elei at'io'n, partly in secitipnnfurther illustrating'my invention; Fig. 3 is aninverted plan of the parts shown in Fig. 2;the heddle bar being omitted for ,clearnes s'; and Fig. 4 is .a sectionon the line dj'a, Fig. 2; I x j Referring to the above drawings ',theframe consists of two parallel b eams l and 2 preferably made of vvoodand secured togetherat their ends by two metallic tie memhere 3 and 4each having holesattheir upper and lower portions through which the endsof two parallel heddle supporting :bars 5 and 6 extend. These bars inthe present instance have-holes at their outer ends for the reception ofspring wire clamps 7 designed toppevent their longitudinal movement.

As a means for supporting the heddle bars 5 and 6 at points within theframe I provide a number of similar devicesshown in detail in Figs. 2, 3and 4, and for their reception the frame beam 1 is recessed at 8 toreceive a fiat metal strip 9 which has its outer face flush with theinner edge 10 of the said beam. Slidably mounted on the outer flatsurface thereon.

of the strip 9 is a Hat sliding metal plate 11 slotted at'12 and 13 andhaving riveted or otherwise secured to it a depending hook 15 placed ata point between said slots. This hook has an opening 16 shap d toreceive the edd e .si pro ti b 5 (F gs 2 (and Q)- The slidahle plate 11'is movably attached to thestr'ip '9 by screws 17 and 1 8 which respectvely pass through the'slots l and 13 and 'enter holes in said strip. Theparts are so arranged and proportioned that when the hook 151s in itsnormal position the screws .will be substantially in the middle of theslots 12 and 13, as shown in full lines in Figs/2 is 3, n the friction btweh the slidable plate 11 and the strip 9 may helreg ulated bytightening or loosening thesescrews.

The heddles may be of any suitable construction and are suspended betvveen the supporting'barso and 6 in the usual manner s th t h y m y be dongi udina y When in use, those heddles which are adacent the hooks 15of the several'supp'orting devices may be conveniently separated by theweaver, since it is merely necessary to push them along thesupportingrods 5 and 6 unt l their pressure against said'hooks issuflicient to move the latter and thereby form an opening through whichthe weaver may insert his to repair or tie any ends of warp whichhavebroken during theweaving v ,1?. iatflon. In Fig. 2 the hook is shown inwe positionso'f which the normal or central is shown in full lines-whilethe broken lines illustrate said hook in a positionfi'nto which it maybe moved.

It'willbe noted (Fig. 3 that by having 7 the contacting faces of theslidable plate 11 and'the metallic strip 9 flat the hook 15 cannot rockor otherwise move beyond the planes of the side surfaces of the framebeams l and 2. This is a very important and valuable feature of myinvention, since' heddle frames oftenhave to ,beplaoed very closetogether and if'a portion of one frame fly fibers which are presentduring weaving, for it will be observed that the strip 9 is set flushwithin the recess of the beam 1 so that any fly fibers settling thereonare either brushed off by the movement of the slidable plate 11 or canbe easily removed. As before stated, different degrees of friction maybe caused between the strip 9 and slidable plate 11 by means of thescrews 17 and 18 and in some cases the friction may be made so intensethat a number of the heddles may be bunched between the upper and lowerhooks; thereby crowding or bunching the warp to produce rib weaves.

In the drawings I have shown a frame having four heddle bar-supportingdevices, two at the top and two at the bottom,.but it will be understoodthat any number may be employed without departing from my invention.

While I have described one of the supporting devices as secured to thebar 1, it will be understood that in securing it to the beam 2, thelatter is. recessed to receive its strip in the same manner as indicatedat 8 in connection with the beam 1, Fig. 2.

I claim 1. The combination in heddle mechanism of a frame; aheddle-supporting bar; a plate having a hook for holding said bar; andmeans for holding said plate in slidable engagement with said frame, thesame being adjustable to vary the friction between the plate and frame.

2. The combination in heddle mechanism of a frame having a flat portion;a heddlesupporting bar; a flat plate slidable on said flat portion ofthe frame and having a hook extending therefrom for holding said bar;and means for holding said plate in sliding engagement with said flatportion.

The combination in a. heddle frame I having a heddle supporting bar of aslidable plate having slots therein; means extending through the slotsfor movably connecting the plate to the frame; and a hook on said plateplaced to hold said heddle supporting bar.

1. The combination in a heddle frame of a member having a recess; a flatstrip fitting said recess; a slidable plate having a fiat surface forengagement with said strip; a heddle supporting bar; a hook on saidplate for holding the bar; and means for limiting the movement of saidplate and for securing it to the recessed member.

5. The combination in a heddle frame of a member having a recess; a flatstrip fitting said recess; a slotted slidable plate having a. flatsurface for engagement with said strip; a heddle supporting bar; a hookon said slotted slidable plate for holdin the bar; with means extendingthrough said slots and strip for securing the plate and strip to saidrecessed member and for limiting the amount of movement of said slidableplate.

6. The combination in a heddle frame of a beam having a recess; a flatplate fitting said recess; a slotted plate having a flat surfaceslidably engaging said strip; screws extending through the slots in saidplate and into said beam; a heddle supporting bar; and a hook rigidlysecured to said slidable plate for holding said bar.

7. The combination in a heddle frame of a beam having a recess; a flatplate fitting said recess; a. slotted plate having a flat surfaceslidably engaging with said strip; screws extending through the slots inthe plate and into said beam; a heddle supporting bar; and a hook forholding said bar rigidly secured to said slidable plate and having aflat surface in contact with a flat surface on the slidable plate.

8. The combination, in a heddle frame having a heddle supporting bar, ofa plate slidably mounted on the frame and having a hook for holding saidbar; and adjustablemeans passing through the plate for varying thefriction between it and the frame.

9. The combination in a heddle frame of a member having a recess; a fiatstrip fitting said recess; aplate having a fiat surface slidablyengaging said strip; a heddle supporting bar; a hook on said plate forhold ing the bar; and means for varying the friction between the flatstrip and the slidable plate.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
